摘要
由于PWM整流的非线性特性,单相电力电子变压器传统的PI控制对参数较为敏感,而滑模变结构控制对干扰和参数具有很强的鲁棒性,因此采用d-q电流解耦方法,构造滑模控制器。搭建3单元级联模块H桥整流器模型,在仿真软件Matlab/Simulink中进行了仿真,并将其同传统的PI控制比较,结果表明了所采用方法的有效性、优越性。
Due to the nonlinear characteristics of PWM rectification,the traditional PI control of the single-phase power electronic transformer rectification stage is more sensitive to the parameters,but the sliding mode variable structure control has strong robustness to disturbances and parameters.So,the dq current decoupling method was used to construct a sliding mode controller.A 3-unit cascaded module H-bridge rectifier model was built and simulated in the simulation software Matlab/Simulink.Compared with the traditional PI control,the results showed the effectiveness and superiority ofthe adopted method.
